Features

- Various attributes and filters like Energy, Frequency, Similarity, Instantaneous, Band pass filters, Absorption quality factor etc…

- Spectral Decomposition with Fourier transforms and Continuous Wavelet transforms

- Mathematical and logical expressions to create your own attributes and filters

- Movie-style parameter testing ( time gate or step out) to quickly find the optimal settings for your attributes

For an overview of the OpendTect Attributes please take a look at the:

OpendTect Attributes Matrix

Convolve

-- Attribute that returns a filtered response

Delta Resample

-- Attribute that enables residual alignment of seismic volumes

Energy

-- Attribute that returns the energy of a trace segment

Event

-- Attribute that quantifies an event's shape or distance relative to a next event

Fingerprint

-- Attribute that computes the similarity between a user-defined vector of attributes and the equivalent vector taken at each position in a cube.

Frequency

-- Attribute that returns frequency properties

Frequency Filter

-- Attribute that returns filtered data using FFT or Butterworth filter types

GapDecon

-- Attribute that aims to attenuate repetitions of primary reflections (multiples).

Horizon

-- Attribute that enables advanced calculations on horizons

Instantaneous

-- Attribute that returns an instantaneous attribute

Match Delta

-- Attribute that extracts time shifts between similar events in different seismic volumes

Mathematics

-- Attribute that returns the result of a user-defined mathematical expression

Position

-- Attribute that returns any attribute calculated at the location where another attribute has its minimum, maximum or median within a small volume.

Prestack attribute

-- This attribute enables you to load, display, use and manage pre-stack data

Reference

-- Attribute that returns the definitions of the extraction position

Reference shift

-- Attribute that moves the extraction position in 3D space

Scaling

-- Attribute used for scaling of amplitude

SEG-Y checklist

-- SEG-Y loading checklist

Similarity

-- Attribute that returns trace-to-trace similarity properties

Spectral decomposition

-- Attribute that returns the amplitude spectrum (FFT) or waveletcoefficients (CWT)

Velocity Fan Filter

-- Attribute that returns energy with apparent velocities inside a specified Min/Max range.
